Bradley Cooper's underwear thieves

UNDERWEAR THEFT: Bradley Cooper reportedly laughed when he heard school girls had stolen his underwear.

Bradley Cooper doesn't mind when his underwear is stolen.

The 'Hangover' star - who is currently dating actress Renee Zellweger - was in Manhattan, New York, shooting for his new movie 'The Dark Fields' when two schoolgirl fans managed to break into his dressing room and raid his belongings.

The two college girls fast-talked their way onto the set by walking in with fake 'Wardrobe Assistant' badges before stealing a pair of his blue polka-dot boxer shorts, while he was on camera.

Security guards chased after the fans - who ran away waving the pants in the air and giggling - but the pair managed to get away in a waiting car.

When the 34-year-old hunk was told of the raid, he reportedly laughed and claimed he was proud of their feat, saying: "Probably one of those sorority dares!"
